City, New York Open Data vs Colorado Information Marketplace
NYC Open Data runs on Socrata; a live keyless GET against the SODA endpoint for the 311 service-request dataset (`data.cityofnewyork.us/resource/erm2-nwe9.json`) returned full JSON with a wildcard `Access-Control-Allow-Origin` header, and the same resource is fetchable as CSV by swapping the file extension. Anonymous reads work without any credential; registering a free Socrata app token is optional and only raises the per-IP throttling limit.
The Colorado Information Marketplace is the state's open-data portal, built on the Socrata platform and covering budget, transportation, public-safety, and demographic datasets from Colorado agencies. Every dataset is queryable through Socrata's SODA REST API without an account, with an optional free app token only needed to raise the anonymous rate limit. Results are returned as JSON by default, with CSV and XML also available per dataset.
